Gleeman Pentaphonic

The Pentaphonic is a five-voice polyphonic analog synthesizer released in 1982.
It was designed by brothers Al and Bob Gleeman and featured three DCOs for a stable
and juicy analog sound. The Pentaphonic was in the running against such classics as
the Sequential Prophet-5, Moog Minimoog and Polymoog, and the Oberheim 4-Voice.
But the Gleeman Pentaphonic (and the Pentaphonic Clear) are extremely rare!
Only about 30 Pentaphonics and 20 Pentaphonic Clears were ever made.

In addition to three oscillators per voice, the Pentaphonic has a four-pole
lowpass resonant filter with an ADSR envelope, a VCA with ADSR, an LFO, and
built-in chorusing (slow or fast). There is also a handy 300-note capacity
sequencer on-board for simple real-time recordings that you can play along with.
There's also a cool X/Y joystick for controlling pitch and mod effects.
Some models also had a Presetter added which gave it 100 patch memories
and eight digital waveforms.

The Clear model is unique because of its transparent plexiglass case. It was also designed to
be strapped on like a guitar for live use. The standard models had a boring black case
and a built-in speaker. Their demise has been blamed on the rise of the digital revolution as led by the Yamaha DX7.
They went out of production in 1983, but the Audities Foundation
had bought, restored and built some since. Audities-built Clear versions have green circuit boards.
They have been used by Moog Cookbook, Imperial Drag, and Alabama.
Originally selling for $2800 to $3400, they now go from anywhere from $700 to $5000 depending
on the condition.
